The musician's ex-wife Paulina Porizkova discovered his body when she and the couple's two sons, Jonathan and Oliver, went to check on him.

"I found him still asleep when bringing him his Sunday morning coffee," Porizkova said in a statement shared via social media. "I touched his cheek to rouse him. It was then I realised that during the night he had peacefully passed on."

"We appreciate the great outpouring of love," she added. "We, his family and friends, are completely and utterly devastated by his untimely and unexpected death and would appreciate the privacy to mourn in private."

Porizkova and the Ocasek family have asked for privacy as they grieve.
